Signature Resources Ltd. has released the results of voting at its annual general and special meeting of shareholders, which was held today. All matters submitted to the shareholders, as set out in the company's notice of meeting and management information circular, were approved with overwhelming support.

Each of the six nominees proposed by management was elected as a director of the company.

The results of such vote are detailed in an attached table.

In addition, at the meeting, shareholders approved: (i) fixing the board of directors at six; (ii) reappointing McGovern Hurley LLP, chartered professional accountants, as the company's auditor for the ensuing year and authorizing the board to fix its compensation; and (iii) reapproval of the company's incentive stock option plan as set out in the management information circular.

The results of such votes are detailed in an attached table.

Update on winter drill program

The company had previously announced its intent to complete a 3,000-metre (m) diamond drill hole (DDH) program with the intent of extending the known mineralization at depth and to the west. With the closing of the oversubscribed equity offering announced on Oct. 30, 2025, the company has modified its program increasing it to eight planned DDHs for a total of approximately 3,900 metres. With the updated modelling completed earlier this year, the company has been able to incorporate a prior 3-D alpha IP (induced polarization) and mag survey that demonstrated a high correlation between mineralization and areas of high chargeability and low resistivity.

The company commenced the winter drill program in early November and has completed approximately 1,312 m of drilling to date. It anticipates closing camp at the end of the second week of December providing a break in the activities, allowing the field crews a chance to recuperate over the holidays and the company will recommence field activities early in the new year.

Extending at depth

The first five DDHs of the winter program are targeted at exploring the extension of the known mineralization at depth.

LM25-01 is a re-entry and extension of DDH LM24-05 that was drilled from the north to the south and appeared to stop at the edge of the low resistivity anomaly, and the company believes it was a cost-effective way to test the depth extensions in the southern edge of the anomaly. The extension to this hole was 240 m to a total drilled depth of 600 m, and samples have been delivered to the lab for assaying and results will be provided when received in the coming weeks.

LM25-02 and LM25-04 will both be drilled on a south to north orientation and are intended to test at depth the extensions of the mineralization. LM 25-02 was completed to a drilling depth of 530 m and the leopard rock package that forms the footwall on the north zone was within approximately five m of where the company had modelled this intercept. Samples for assaying have been delivered to the lab and results for LM25-02 are pending. LM25-04 will be collard to the south of LM25-02 by approximately 100 m with a planned drilling depth of 675 m. It is anticipated that LM25-04 will be completed following the holiday break.

LM25-03 has a planned drilling depth of 600 m drilling a south to north orientation. This hole is targeting the area where DDHs 24-06 (1) and 24-07 (2) demonstrated that the north and central zones were converging creating a wider area of mineralization. This hole is 90 per cent complete and the company anticipates having the samples delivered to the lab for assaying before the holiday break.

LM25-05 has a planned drilling depth of 500 m and will have a southwest-to-northeast orientation with a goal of avoiding the mildly easterly dipping diabase dike. This hole is targeted because of the nearly 50 m wide occurrence of the south zone at surface, which also correlates strongly with the wide intercepts of DDH's LM24-09 (3) and LM24-10 (4), which showed wide intercepts in the same zone just west of the postmineralization diabase dike. LM 25-05 will not only test the depth extension of the south zone but will also test the extension of the north zone.

Extending laterally to the west

The final three holes of the winter drill program are targeted at extending the known mineralization laterally to the west. If LM25-08 is successful, it will demonstrate the continuation of the mineralization, 600 m to the west of the 1.6-kilometre (km) conceptual pit modelled in the company's recently published National Instrument 43-101 report.

LM25-06 and LM25-07 are being drilled. Two targets are 290 m west of the final two DDHs drilled in 2024. LM 25-06 has a planned drilling depth of 350 m and will target the northern edge of the low-resistivity anomaly. LM25-07 has a planned depth of 500 m and will test the large heart of the anomaly below the identified target DDH-5.

LM25-08 will be collared 300 m farther west with a planned depth of 500 m with a south-to-north orientation. This drill hole will also be testing the heart of the low-resistivity anomaly, similar to LM25-07, and further extending the mineralization laterally to the west.

About Signature Resources Ltd.

The company is a Canadian-based advanced-stage exploration company focused on expanding the 100-per-cent-owned Lingman Lake gold deposit, located within the prolific Red Lake district in Northwestern Ontario, Canada. The Lingman Lake gold property consists of 1,274 single-cell and 13 multicell staked claims, four freehold fully patented claims and 14 mineral rights patented claims totalling approximately 24,821 hectares. The property includes what has historically been referred to as the Lingman Lake gold mine, an underground substructure consisting of a 126.5 m shaft, and three levels at depths of 46 m, 84 m and 122 m. There has been over 43,222 m of drilling done on the property and four 500-pound bulk samples that averaged 19 grams per tonne (g/t) gold (Au). The company's initial mineral resource estimate was published in the report entitled "NI 43-101 Technical Report on the Lingman Lake Property," dated May 31, 2025, prepared by Gehard Kiessling, PGeo, Farshid Ghazanfari, PGeo, Marin Drennan, PEng, Cameron Finlayson and Jeff Plate, CFA, PGeo, of Watts, Griffis and McOuat Geologic Mining Consultants. The initial mineral resource published was estimated to contained 2,145,000 tonnes of material grading 1.38 g/t Au for an estimated 95,200 ounces in the indicated category and 18,398,000 tonnes of material with an average grade of 1.14 g/t Au for an estimated 674,320 ounces in the inferred category at a cut-off grade of 0.30 g/t. The company is focused on rapidly expanding the known mineralized envelope with its 100-per-cent-owned diamond drilling rigs. In November, 2023, Wataynikaneyap Power energized a new 115-kilovolt high-tension transmission line within 40 km of the historic Lingman Lake mine.

(1) As reported in a news release dated Jan. 10, 2025, LM 24-06 returned results in the central zone of 54 m with an average grade of 1.14 g/t Au, including one m intercepts of 9.97 g/t Au, 7.16 g/t Au and 17.69 g/t.

(2) As reported in a news release dated Feb. 6, 2025, LM24-07 returned a north zone intercept of 47 m with an average grade of 2.43 g/t and a central zone intercept of 19 m with an average grade of 4.71 g/t Au.

(3) As reported in a news release dated Feb. 18, 2025, LM24-09 returned a south zone intercept of 51 m with an average grade of 1.81 g/t Au, including a four m intercept with an average grade of 4.4 g/t Au and a six m intercept with an average grade of 5.34 g/t Au.

(4) As reported on Feb. 18, 2025, LM24-10 returned results of 34 m with an average grade of 1.8 g/t Au, including a six m segment with an average grade of 7.7 g/t Au.
